CVE-2024-50169

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-50169
In the Linux kernel, the following vulnerability has been resolved: vsock: Update rx_bytes on read_skb() Make sure virtio_transport_inc_rx_pkt() and virtio_transport_dec_rx_pkt() calls are balanced (i.e. virtio_vsock_sock::rx_bytes doesn't lie) after vsock_transport::read_skb(). While here, also inform the peer that we've freed up space and it has more credit. Failing to update rx_bytes after packet is dequeued leads to a warning on SOCK_STREAM recv(): [ 233.396654] rx_queue is empty, but rx_bytes is non-zero [ 233.396702] WARNING: CPU: 11 PID: 40601 at net/vmw_vsock/virtio_transport_common.c:589

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: vsock: Actualizar rx_bytes en read_skb() Asegúrese de que las llamadas a virtio_transport_inc_rx_pkt() y virtio_transport_dec_rx_pkt() estén equilibradas (es decir, virtio_vsock_sock::rx_bytes no mienta) después de vsock_transport::read_skb(). Mientras esté aquí, también informe al par que hemos liberado espacio y que tiene más crédito. Si no se actualiza rx_bytes después de que se saca el paquete de la cola, se genera una advertencia en SOCK_STREAM recv(): [ 233.396654] rx_queue está vacío, pero rx_bytes no es cero [ 233.396702] ADVERTENCIA: CPU: 11 PID: 40601 en net/vmw_vsock/virtio_transport_common.c:589
